COMBINED PULVERIZER AND ROLLER.

SPECIFICATION forming part of Letters Patent N o. 510,166, dated December 5, 1893.

Application filed June 5, 1893. SarialNo. 476,625. (No model.)

My invention relates to improvements in agricultural machines, and to that particular class thereof known as pulverizers.

The objects of myinvention are to produce a machine of this class of cheap and simple construction, light of draft, and adapted to thoroughly crush, pulverize, and roll the soil;

to provide for a raising and lowering of the pulverizer, whereby the same may be thrown out of and into operative position, and for a convenient turning of the machine when the same is of large size.

Various other objects and advantages ofV the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawingsz-Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a plan view thereof, one of the main rollers being shown in horizontal section.

Like numerals of reference indicate like parts in all the figures of the drawings.

The draft frame of the machine comprises the side bars 1, which are connected by the transverse bars 2, the said transverse bars having secured to their centers the draft-pole 3 which is made rigid through the medium of braces or hounds 4. leading from the draftpole and secured to the transverse bars 2.

The machine frame comprises the opposite side frame bars 5 connected by the transverse bars 6 and 7, the same being spaced apart asuitable distance and located near the rear ends of said frame bars.

The machine frame is narrower than the draft frame, and the front ends of the bars 5 are embraced by the rear ends of the bars 1.

Depending from the rear ends of the bars 1 are clips 8, and aligning therewith and rising from the front ends of the bars 5 arecorresponding-clips 9.

bearings for a transverse axle or shaftlO, which serves to loosely hinge together the frames described and also serves to accom- These clips 8 and 9 forniV modate the main .roller of the machine. In instances where the machineY is'narrower, or in the lighter constructions of these machines, but one main roller is necessary, but in the wider machines, an example of which I have illustrated, two main rollers ll are accommodated by the shaft or axle 10. Each roller consists of a pair of circular metal frames 12, which at their inner sides or faces near their peripheries are provided with rabbets or grooves 13 which accommodate the tongued ends of the transverse boards 14 and prevent the said boards, which it will be understood form the covers or casings of the rollers, from getting loose. The hubs 15 of the frames 12 are loose upon the shaft or axle 10, and at their inner sides or faces are toothed as at- 16, the teeth being inclined. Y

Collars 17 are formed upon the shaft or axle 10 at each side of the center of the latter, and arranged beyond the collars or between them and the hubs, are clutch-sleeves 18, the same having their outer ends provided with inclined teeth oppositely disposed to those of the hubs and adapted to engage the same when the rollers rotate 'forwardly or to ride thereover when said rollers rotate rearwardly, so that when the machine moves forward the shaft or axle is rotated, and when in the act of turning, the said shaft or axle remains stationary. In order to insure the engagement of the clutch-sleeves with the hubs coiled springs 19 are interposedbetween the collars 17 and the inner ends ofthe clutch-sleeves.

In suitable bearings between the cross .bars

6 and 7- of the machine frame there is jour-V maybe employed in connection with the shaft 20, but I prefer to mount upon this shaft atl the center and near the ends the disks 24,V

and to secure to these disks a seriesof spirally disposed strips 25, each strip being given a one-half twist more or less in its course IOO around the disks and provided at intervals with curved pulverizing teeth 26. A bar 27 is secured to the front face of the transverse frame bar 7, and is provided with a series of spring-wire teeth 2S which alternate in their location with the teeth 26 and serve to comb the trash from the teeth of the pulverizer roll as the same pass successively through the spaces thereinbetween. In this wayaccumulations of trash are avoided and the pulverizer teeth are kept clear and in condition to operate.

At the rear ends of the bars 5 in slotted bearing arms 29 a rock-shaft 30 is journaled, and the same at its ends beyond its bearings is provided with rock-arms 3l which have pivoted at their outer or rear ends at 32 pairs of links 33. These links are connected pivotally as at 34 with journal arms 35, between whose ends there is journaled a rotatable shaft 36 upon which is located a land roller 37.

A platform 3S covers the pulverizer, and is hinged as at 39 to the cross bar 6. This platform supports a standard 40 that rises from its center, and upon the latter is mounted a seat 4l for the accommodation of the driver. Within easy grasp of the driver when perched upon his seat is a hand-lever 42, the same being made rigid with and rising from the transverse rock shaft 20, so that through the mediuin of said lever the rock-shaft may be operated, and thus the land roller 37 borne upon and consequently the rear end of the framework elevated, or by a reverse movement of said lever the framework may be lowered, and in this manner the pulverizer thrown into and out of operative position. Alocking pawl 43 of ordinary construction is carried by the hand-lever and at its lower end is designed to engage a convenient notch of a series formed in a segmental locking standard 44. A slotted arm 45 is secured to each of the frame bars 4 and bolts 46 pass through the slots of the arms, whereby the latter are adjustable up and down. These arms are provided with pulleys 47, whereby the sprocket chains or belts 22 that communicate motion from the master sprocket wheels 23 to the small sprocket wheels 2l, may be adjusted. This completes the construction of the machine, and the operation is as follower-When going to or from the field of operation the hand-lever 42 is thrown to the rear, whereby the pulverizer cylinder is elevated from contact with the ground, and the machine travels upon the rollers 1l and 37. When the field of operation has been reached, the lever 42 is swung to the front a desired distance so as to lower the pulverizer cylinder, whereby its teeth may take a desired distance into the soil. As the machine moves along the main rollers 1l crush any growth, hard lumps, or clods of earth that lie in their path, after which the soil thus produced is minutely pulverized by the rapidly rotating pulverizer, the teeth of which are in a manner' heretofore described kept clear of trash. Following the pulverizer comes the land-roller 37, the same serving to smooth the soil thus pulverized.

I do not limit my invention to all the precise details of construction which I have herein shown and described, but hold that I may make such variations in such details as may be found necessary without departing from the principle or sacrificing any of the advantages thereof.

Having described my invention, what I claim is-n l. In a machine of the class described, the combination with a frame, crushing rollers carried thereby, a pulverizer arranged in rear of the crushing rollers, of bearings at the rear ends of the frame, a rock-shaft arranged in the bearings, a lever extending from the rockshaft, a locking standard at the side of the lever, a pawl carried by said lever, rock-arms for the shaft, links pivoted to the rock-arms, bearing arms connected to the lower ends of the links and extending rearward from the frame, and a land roller journaled in said bearing arms, substantially as specified.

2. In a machine of the class described, the combination with a suitable framework, of bearings in the frame, of opposite verticallyadjustable bearings, a rock-shaft arranged in the bearings, a lever extending from the rockshaft, a locking standard at the side of the lever, a pawl carried by said lever, rock-arms for the shaft, links pivoted to the rock-arms, and bearing arms connected to the lower ends of the links and to the lower ends of the bearing brackets, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

GEORGE R. FARMER.
